Crystals: Q 25,0-JXS21-12-10/15-T1-FU-WA-LF Application Field and Working Principle

Crystals are widely used in both industrial and consumer application fields. This article is going to discuss the application field and working principle of Q 25,0-JXS21-12-10/15-T1-FU-WA-LF, a type of crystal.The Q 25.0-JXS21-12-10/15-T1-FU-WA-LF crystal belongs to a class of temperature-compensated crystal oscillators (TCXOs). It is a high-precision temperature-compensated crystal oscillator (TCXO) designed and manufactured by Citizen Electronics Co., Ltd. The nominal frequency of the crystal is 25.0 MHz and it is designed for the frequency band of 10/15 MHz. It is manufactured in 25 ppm (parts-per-million) accuracy and within the temperature range from 0 to 70 ˚C. The TCXO is an electronic component with excellent frequency stability, highly precise temperature compensation, wide temperature range and a wider frequency range. It is mainly used in GPS modules, PDAs, smartphones, and other electronic products with short communication distances. The temperature-compensated quartz crystal oscillator works on the principle of thermal concentration compensation, and uses a temperature-compensated circuit to compensate the frequency shift caused by temperature change, thus achieving the purpose of stabilizing the output frequency. The oscillator comprises a quartz crystal unit, a temperature-compensated circuit, an oscillator coil, an amplifier and a frequency divider. The quartz crystal unit forms the equivalent of mechanical resonator in the oscillator circuit. The electrical oscillator is produced by the crystal unit. The oscillation signal generated is amplified by the amplifier and passed through a frequency divider. After the signal is sent to the temperature-compensated circuit, the signal is stabilized by the temperature-compensated circuit with temperature compensation, resulting in an output signal with good accuracy and stability. The crystal oscillator consists of a quartz crystal and a temperature-compensated circuit. The quartz crystal is used to provide high-precision clock signals with low jitter. The temperature-compensated circuit is a component used to adjust the frequency of the signal from the crystal oscillator. It can effectively adjust the frequency change caused by temperature changes, so that the output frequency can remain stable. The application field of the Q 25.0-JXS21-12-10/15-T1-FU-WA-LF temperature-compensated crystal oscillator covers a wide range, including GPS modules, PDAs, smartphones, and other electronic products with short communication distances. With its excellent performance, high accuracy, and wide frequency range, the crystal oscillator is suitable for the design and manufacture of sophisticated components with low jitter and high precision. In conclusion, the Q 25.0-JXS21-12-10/15-T1-FU-WA-LF temperature-compensated crystal oscillator is an excellent choice for applications requiring accurate and stable frequency output. With its wide frequency range and temperature compensation capability, it provides excellent performance in the fields of GPS modules, PDAs, smartphones, and other electronic products with short communication distances.
